    ping a little oil flow out of corrugated pipe, put a container under it. The method is suggested to be applicable to other maintenance of hydraulic components. Article VI Solenoid valve In this Article a switch, controlled by electric components, is installed at inlet or outlet of measurement transducer, which is used for ensure the accuracy of presetting filling volume of fuel dispenser. Nozzle cannot be closed after finishing presetting volume due to the inertia of pump and pressured oil, which results in that real volume exceed presetting volume so as to affect fuel dispenser’s accuracy. In order to prevent this phenomenon occurring, most of manufacturers of fuel dispenser adopt to mount a solenoid valve at inlet or outlet of measurement transducer, switching off valve prior to presetting volume getting reach through regulating appropriate ahead volume. The method is one of the most efficient measures that used for ensuring fuel dispenser’s accuracy and preventing overrun resulted from the inertia of pump and pressure oil. There are two kinds of solenoid vale --- membrane type and piston type. The former, simple structure and high anti—pollution, is closed through membrane. However, its performance is depended upon the technology about membrane and weather. The latter valve controlled through piston has wide applicable range of temperature, weak to anti-jammed pollution. Double flux solenoid valve is controlled by the position movement of cam that is driven by motor, and large or small flux is realized through the open or closed of main or vice valve. It has merits of wide applicable temperature range, high pollution-resistant. At present, most manufacturers adopt double flux membrane solenoid valve in fuel dispenser. Double flux solenoid valve Structure and working principle Membrane sole fuel dispenser noid valve is widely adopted recently, which also called double flux solenoid valve, shown in Diagram 2-35 and 2-36.

    nyrak settlement on the outskirts of the country s biggest city, Almaty, involved entire families and shocked both officials and the public. It showed that there is an unexpected potential for social unrest in this oil-rich country with its booming economy. People in Kazakhstan are usually indifferent to politics, and tend to ignore calls from the opposition to rally in support of democracy. But it seems that they will put up a fierce fight in defence of their homes. And there may be more to come. Shanyrak is only one of up to 14 illegal settlements to have sprung up in and around Almaty over the past 15 years, with an estimated total of 70,000-100,000 inhabitants. Similar settlements surround other large cities, notably the capital, Astana. Although Kazakhstan is a multi-ethnic country of 15m, where Kazakhs became the majority only in the late 1990s, all of these settlers are Kazakhs. People from Russian or German ethnic backgrounds could return to their homelands during the economic depression of the early post-Soviet years. The only way out for Kazakhs from the impoverished countryside was to move to the cities in search of opportunities. Having little or no money, they settled on open land within or just outside the city limits. Some acquired documents by bribing local officials; others were too poor even for that. Yet for many years, they lived undisturbed. This relaxed approach was pioneered by the previous mayor of Almaty, a Russian, who may have been loth to see his image tarred by evicting Kazakhs. The current mayor, Imangali Tasmagambetov, a Kazakh, has had no such qualms. With Almaty now experiencing a construction boom, clearing away the settlements has become a priority. For the present, at least, the wholesale demolition is on hold. The people of Shanyrak are seeking to leg fuel dispenser alise their properties, though the outcome of these efforts is uncertain. Yevgenii Zhovtis, a human- rights activist, says he hopes that the authorities have learnt a lesson. But, he adds, “I am concern fuel dispenser fuel dispenser
